Researchers move closer to faster-charging Li-ion batteries; real-time tracking of Li ions in LTO

Green Car Congress

A team of scientists led by the US Department of Energy’s (DOE) Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging battery electrode material made of lithium, titanium, and oxygen.

New group of materials could lead to faster-charging Li-ion batteries

Green Car Congress

The researchers, led by Professor Clare Grey, found that lithium ions move through the materials at rates that far exceed those of typical electrode materials, which equates to a much faster-charging battery. The maximum power output and minimum charging time of a lithium-ion battery depend on both ionic and electronic transport.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.

SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

Instead of using machine learning just to speed up scientific analysis by looking for patterns in data—as typically done—the researchers combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.
